Application nledMarch 4, 1916.

To all whom 'it may concern Be it known that I, JACOB E. IVmsnL, acitizen of the United States, residing at Shelby, in the county ofRichland and State of Ohio, have invented. new and useful Improvementsin Stovepipe-Fasteners, of which the following' is a specification.

This invention relates to certain new and useful improvements in devicesadapted for firmly securing a stove pipe within a. flue thimble, and atthe same time limiting the insertion of the stove pipe within the fluethimble.

The primary object of the invention is the provision of a device of theabove stated character wherein means are employed for contracting theclamping band automatically and into clamping engagement with the smokepipe upon the insertion of the pipe within the flue thimble and saidmeans at the same time controlling the inward movement of the pipewithin said flue thim ble whereby a perfect draft will be obtained atall times.

With the above and other objects in view,

the invention consists in the novel features, details of constructionand combination of parts which will hereinafter be more fully set forth,illustrated in the accompanying drawing and pointed out in the appendedclaim.

Figure 1 is a view in perspective showing my improvement as applied to aflue thimble; Fig. Z is a sectional view illustrating the open positionof the clamping band; F ig. 3 is a longitudinal section taken throughthe thimble clearly illustrating the operating means for the band; andFig. 4 is a vertical section illustrating the band in clamping position.

Referring more particularly to the accompanying drawing, in which likecharacters of reference denote corresponding parts in the several views,5 denotes a flue thimble having disposed therein a split annularclamping band 6 preferably constructed of sheet metal and having itsmarginal edges reinforced by turning the edges of the band upon itselfand indicated by the reference character 7. The object of this clampingband is to automatically clamp the stove pipe 8 and firmly hold the samewithin the thimble 5 and prevent the pipe from working loose or becomingdislodged from the chimney flue, and to this end I pivotally connect thefree ends 9 of Specification of Letters Patent,

serial No. 82,169.

the clamping band 6 to L-shaped ends 10 of a pair of L-shaped togglelinks 1Q, by means of pivot pins 11, while the toggle links at their'opposite ends overlap one another and are pivotally connected inoverlapped relation one to the other by means of the pivot pin 13 to alongitudinally movable operating bar 14. Each of these toggle links areprovided with slightly curved guide slots 15 adapted to receive thebolts 16, said bolts serving to spread and close the toggle links uponthe operation of the bar 14. These bolts are inserted through the fluethimble and are positively retained thereon by means of the nuts 17,said nuts engaging with a wear plate 18 to prevent the nuts from depressing or marring the thimble to any eX- tent upon the tighteningaction thereof. The said operating bar 14 is operable in a straightlongitudinal line -within the thimble 5 and is provided on its inner endwith an upwardly and forwardly turned hook 19, the purpose of which isto obstruct the insertion of the stove pipe 8 within the flue and beengaged by its inner end, whereupon a further movement of the stovepipe-within the thimble will cause an inward movement of the operatingbar, which in turn will rock the l shaped toggle links on their pivotand cause the band to contract circumferentially and clamp the band incontact with the Patented Sept. 5, 1916,

outer circumference of the stove pipe 8.

lVhen it is desirable to release the stove pipe from the thimble thesame is accomplished by grasping and pulling on the manipulating member20 loosely connected to the forward end of the operating bar.

From the foregoing description, taken in connection with theaccompanying drawing, the advantages of construction and of the methodof operation will be readily apparent to those skilled in the art towhich the invention relates, and while I have de scribed the principlesof operation of the device together with the device which I now considerto be the best embodiment thereof, I desire to have it understood thatthe device shown is merely illustrative and that such advantages may bemade when desired as are within the scope of the claim appended thereto.

I claim:

The combination with a flue thimble, and a split band adapted to clamp astove pipe within said flue thimble, of means for operating said band,said means comprising a hook member movable longitudinallyD Within thethimbie and adapted for engagement With the inner end of a stove pipe, apair of Slotted members pivotaily connected at one end to the hookmember and pivotally connected at their opposite ends to the terminalsof the band and operable upon movement of the hook member in onedirection to cause ay ,clamping action 01": the band around and Withsaid pipe, and upon movement of the hook member in the opposite JACOB E.WEISEL.
